We have a page containing a list part. One of the actions in the list part is updating data in the line that also modifies parent data. Imagine for example, that the action updates line weight that implies also modifying parent weight (that is the summation of lines weight).
Parent data is correctly modified. However, parent weight data that is shown in the page still contains old data. In this situation, if you try to change any other field in the page, the following error raises:
We would need to set the property UpdatePropagation of the listpart to Both. However, the listpart is part of BC code and this property is NOT allowed to be modified in an extension. We don't consider a good idea clonning the listpart just to change that property value.
Is there any other workaround that will update the page from the subpage? We have tried calling page.Update(false) but have no success (perhaps not in the correct trigger).
Any suggestions will be appreciated. Thanks in advance!
